 German Physicist  Began his research as a high school math teacher.  Noticed a relationship between the voltage potential difference and current  His findings have greatly influenced the study of current electricity.

I=∆V/R V – Voltage, Volts (V) I – Current, Amps (I) R – Resistance, Ohms ( Ω )

 I=∆V/R  What type of relationship is this?  What will happen if the voltage is constant and we increase the resistance?  What do you think would happen if we keep the current constant and increase the voltage?

 I =∆V/ R  V=IR  Slope=?

 Mud  Microorganisms in the mud  Electrons from anaerobic microbes  Electron Transport Chain. hill.com/sites/ /student_view0/chapter25/animation__electron_transport_system_and _formation_of_atp__quiz_1_.html

 Anaerobic Bacteria Chemical energy from bacteria is turned into electric energy Electron transport chain Convert fuel to energy

 What did you think would happen?  What have your readings been?  What do you think will take place next?

c Mud Battery

 The magnitude of the current and the direction of positive current.  The Power that your battery produces.  …

 What are the benefits or disadvantages, if any, of using a mud battery?  What would happen to the readings if: the electrode surfaces were doubled? the mud volume was doubled? the time were increased?

 A team of students from CPP and Cal Poly SLO  Studied life in extreme environments, Analogous to Mars
